'It's been insane here': People are lining up in droves to prepay property taxes before the GOP tax law kicks in

Republicans' tax overhaul, which President Donald Trump signed into law last week, caps state and local tax deductions at $10,000.

Ahead of the change, which takes effect Monday, taxpayers can prepay their property taxes for next year to save money.

Homeowners across the US are rushing to do just that.

Municipalities around the US this week have seen a surge in homeowners prepaying their property taxes as they brace for a major change in deductions from the Republican tax law that will take effect Monday.

President Donald Trump signed the tax bill into law last week after months of legislative wrangling on Capitol Hill, marking one of the most drastic overhauls of the federal tax code in decades. The law eliminates the Affordable Care Act's so-called individual mandate, opens parts of Alaska up to oil drilling, and upends the tax code for individuals and businesses, among other changes.

But many high-end homeowners could be paying more in property taxes next year because of a new rule that caps the amount of state and local tax deductions at $10,000. Since there is currently no limit on this deduction, people are rushing to prepay their property taxes before the cap kicks in at the turn of the new year.

From Virginia to Massachusetts, and New York to California, municipalities — mostly in areas with higher levels of state and local income taxes — have seen a stunning increase in property-tax receipts in recent days.

"It's been insane here," James McAuliffe, the town treasurer in Milton, Massachusetts, told The Wall Street Journal. "Thank you, Mr. Trump, for solving my cash-flow issues. It's become a very expensive town."

High-income taxpayers who itemize their deductions currently benefit the most from the unlimited state and local tax deduction, commonly referred to as SALT deduction. Individuals with incomes greater than $100,000 make up roughly 90% of the deduction's beneficiaries, according to an analysis by the Tax Foundation.

This means homeowners in high-income and high-tax states like New Jersey, New York, California, Illinois, Texas, and Pennsylvania will bear the brunt of the change.

The Republican tax bill marks the culmination of Trump's first major legislative achievement as president nearly one year into his first term.
